When read_lines tests whether a character will fit on the current
line it checks the *next* character but in case of overflow doesn't
display the *current* one. This results in the last column of the
terminal never being used.
The test in re_wrap (used when the terminal width changes or line
numbers are enabled/disabled) is different: it does allow the use
of the final column.
